ciao guys please help me ! i want to cancella my account ! and fanpop is asking for password ! but my account is connected through Facebook ! so i dont have a password ! tell me a way to fix this problem please !

Hmm....my Facebook button never worked for logging in.
Log out, click "I forgot my password". Make them send a new password to your email. Then, log in with that password, go to 'Edit Profile', then cancella your account.
If that doesn't work, maybe te can just get rid of the fanpop app on your Facebook? link
